Had to unplug my charger and the car sat in the PHX sun all day. Can confirm, hybrid battery temp of 122 gave a "stop now" message.
Changed to "severely limited performance" with a red turtle at 121-120F. When it switched the battery indicator (which was up above 99%) showed 0 miles range and began counting up to 95+ miles.
At 118-117F the turtle went yellow and just "limited performance"
At 114-113F the warnings went away but AC was still fully redirected to the battery loop.
At 112-111F, the AC began working in the cabin.
